Banking Regulation and Supervisory Framework
What this domain tests
This domain tests the legal and supervisory architecture that defines who may bank, who examines banks, and how supervisors intervene before capital or liquidity weakness harms depositors and the deposit insurance fund. Expect questions on charter choice, regulator jurisdiction, the supervisory cycle, CAMELS, prompt corrective action, and the difference between safety-and-soundness supervision and consumer or financial-crime oversight.
Core rules and concepts
- Charter choice drives primary federal supervision: a national bank is supervised by the OCC; a state-chartered insured bank has its state regulator and the FDIC; a bank holding company is supervised by the Federal Reserve. The insurer is not always the primary examiner.
- Supervisors use risk-focused examinations, offsite analytics, and continuous monitoring. CAMELS covers capital, asset quality, management, earnings, liquidity, and sensitivity to market risk; the composite rating is a supervisory judgment, not a mechanical average.
- Prompt corrective action ties capital categories to restrictions. Well capitalized generally requires total risk-based capital of 10%, Tier 1 risk-based capital of 8%, CET1 of 6.5%, and a leverage ratio of 5%. Lower categories trigger increasingly severe limits on brokered deposits, asset growth, capital distributions, and expansion.
- Informal and formal actions differ. A matter requiring attention is supervisory feedback; a cease-and-desist order, consent order, or civil money penalty is a formal enforcement tool.
Worked example
A bank reports CET1 of 7.0%, Tier 1 risk-based capital of 8.5%, total risk-based capital of 11.0%, and a leverage ratio of 4.8%. It meets the three risk-based well-capitalized thresholds but fails the 5% leverage threshold. The bank is adequately capitalized, not well capitalized, despite strong risk-based ratios. It may need a waiver to accept brokered deposits and faces limits on capital distributions and growth. The reasoning must start from the weakest applicable PCA threshold, not from the headline total capital ratio.
Traps that cost marks
- Assuming the FDIC examines every insured bank; it is primary examiner mainly for state nonmember banks.
- Treating the CAMELS composite as an arithmetic average of component ratings.
- Confusing capital adequacy with liquidity or earnings strength in a PCA question.
- Calling a supervisory letter a formal enforcement action.
- Ignoring that state and federal requirements can both apply.
